Export all workouts at once (bulk import/export, backup):
If you want to back up all your workouts from the Endomondo servers you can use the site www.tapiriik.com. It's created by a Collin Fair from Canada, who has done a great job of integrating various fitness trackers and Dropbox.
As an exception, we've given him access to our API, so we can do the syncing properly. Signing in to Tapiriik with your Endomondo and Dropbox accounts will ensure that everything is backed up properly.
You can also use the site, if you want to move to Endomondo from one of the other fitness trackers and want to take your workouts with you.
Important: In order to avoid duplicates when connecting your account with Tapiriik via Dropbox, please remember to click “reconfigure” and untick the send activities to Endomondo box (as this option is ticked by default). Otherwise your Endomondo account will be filled with duplicates and the user will be responsible for deleting these duplicates (we do not have a bulk delete tool available at the moment and these workouts will have to be deleted one by one)
